Narali Poornima, or Nariyal Purnima, is an auspicious festival and ritual observed on full moon day in Shravan Month. In 2015, the date of Narial Purnima is August 29. On this day Narials, or coconuts, are thrown into the sea to propitiate Varuna, the sea-god. The festival is most popular along the Maharashtra coast.

The festival is mainly observed by fishermen, especially by the Kolis in Western coast of India. The day also marks the gradual retreat of the monsoon winds. This helps the fishermen to venture into the sea. In another interpretation, the ritual of throwing coconuts is to seek the blessing of the sea god for a good catch and happy life.

Coconut is offered because it is considered to be the purest offering to gods. The water and the kernel inside the coconut are considered to be unadulterated.

There is also another legend associated with the Narial Purnima it suggests the ritual is a sort of thanksgiving to Lord Varuna for holding aloft the bridge that enabled Lord Ram to go to Lanka in epic Ramayan.
